Allegedly when Judas found out Jesus was to be crucified he tried to return the money. I guess because he regretted it? He committed suicide allegedly.
But there is another theory. That Judas did what he did at the request of Jesus. How that flies I don't know.
But..and here is the great IRONY.
The crucifixion and resurrection was the gateway to human salvation. Turned out to be short-lived temporary. Why wasn't it permanent? And why should an act of someone else be the cause of one's salvation? Why isn't that up to the individual to lead a good life a true life a just life an honorable life? Why is it the job of others to insure that? More passing the buck of responsibility. Never ending. Never changing. TRANSFERENCE.
